Which is faster simple diffusion or facilitated diffusion?

Biology
1 answer:
Ronch [10]3 years ago
3 0

Facillatated diffusion is faster than simple diffusion when solute concentration is low because it uses channels to transport molecules throught the lipid bilayer. Simple diffusion depends upon concentration gradients so the net movement of diffusing molecules depends on the concentration gradient, thus the rate of diffusion is directly proportional to the concentration gradient.

Providing immunity by injecting the body with a weakened form a pathogen is known as
blagie [28]

Answer:

vaccination

Explanation:

The vaccination has been one of the most revolutionary inventions in the medical field. This invention helped protect people from numerous diseases, some being totally neutralized, while some having only minor effects on the human body. The vaccination basically is a way of enhancing the immune system of the body by injecting in it a weakened form of the pathogen. In this way, the weakened form of the pathogen is not capable to harm the body, and the body is not fighting against it, but instead the pathogen becomes part of the body and its defense mechanism, so when the pathogen strikes, the body has a counter attack and defeats it.

Answer:

fast- flowing areas usually contain more oxygen than slow-flowing ones.

Explanation:

looking at the statement that accurately compares fast-flowing and slow-flowing areas of stream and water, we need to understand how they flow. a stream flow downhill and it can also flow in a perfect channel, except when flooding occurs and water overflows its channel and spread out across the area of the land. so, fast-flowing generally have higher levels of dissolved oxygen more than slow-flowing because slow-flowing are aerated.

If red foxes were to go extinct, what would be the two most likely effects on the ecosystem
wel
Red foxes are omnivores. Their diet includes small animals such as  birds, squirrels, rabbits and mice, but also berries, grasses and insects such as crickets, caterpillars, grasshoppers and beetles. Red foxes are therefore primary as well as secondary consumers, and even apex predators. Their removal from an ecosystem would most likely reduce the predation pressure on small animals and insects, and may result in population explosions of these prey animals. This in turn may result in additional pressure on the ecosystem as these animals exceed the carrying capacity, and could lead to other plant and animal species within the food web being decimated. Basically, the balance of the ecosystem would be lost until a new equilibrium can be established.

How do farms affect oxygen levels in the ponds
joja [24]

Answer:

The oxygen-rich surface water blends with the deeper, depleted water. The dissolved oxygen concentration in the mix can be too low to support life in the pond. Both fish and plankton can die from low dissolved oxygen following a turnover. ... Thus, turnover can happen if a cold rain and wind cools the surface wate
